Hood scoops are not the only method used to draw in air from the outside of the vehicle. If someone is not interested in cutting up or replacing their factory hood they can take other routes that will maintain the factory appearance, such as:
Cold Air Intake: The factory induction system on Challengers is designed to draw in cold air from outside of the car. They don’t run to the outside of the car though; they simply draw in air from an area of the engine bay where cold air is made available. True cold air intakes can be installed that do draw in air directly from the outside.
Hood Vents: Installing hood vents to draw in cold air is an easy, cheap, and effective manner to bring cold air into the engine bay. The amount of air that can be drawn in by this method is limited though and will not be as effective as a large hood scoop.
Hellcat Intake: Hellcats made use of the headlights to double as a route for air to be drawn into the intake system. Setting up a similar system on any Challenger won’t bring down the temperature of the engine bay but will offer cool air up to the engine as a cold air intake would.
